The Athletics’ number one pitching prospect A.J. Puk underwent successful Tommy John surgery April 10 to repair ligament damage in his left elbow and will now miss the remainder of the 2018 season. The setback also puts 2019 in jeopardy for the 22-year-old lefty who was having a great Spring Training and was even in consideration for the Oakland’s fifth rotation spot after averaging 12 strikeouts per nine innings. Puk posted a 3.38 ERA with seven Ks in 10 2/3 innings of work, including not allowing an earned run in his first three appearances this season.

Bader has a seven-game hitting streak going into tonight’s game with the New York Mets and has hit and scored in four straight games as he continues to fill in for injured players in the Cardinals outfield. The Cards are 9-5 with Bader in the lineup and his recent hot streak has boosted his batting average to .300. Bader has proven to be a beast on the base paths as well with two stolen bases this week for a total of three on the season.

Disco, who is on the 60-day DL with a left oblique strain, was scheduled to throw off a mound in a bullpen session Wednesday. DeSclafani was injured early in March, so he’ll essentially need to go through his own Spring Training before returning. “It’s slightly different because of the nature of the injury,” Reds manager Bryan Price said. “You do everything you can to make sure the injury is 100 percent healed, but you’re trying to introduce baseball activity through the course of that healing and not do too much. He will have to re-establish a workload, starting with bullpens, live batting practice and then games that will build him up to that roughly 90-100 pitch threshold.” The righty is eligible to come off the DL May 28.

Red Sox pitcher Brian Johnson come on to pitch three innings in relief against the Angels last week and allowed just one hit. Johnson also had three strikeouts in the game and now carries an ERA of 2.08 and a 1.31 WHIP for the season.

Red Sox relief pitcher Austin Maddox is on the 10-day DL as he continues to deal with shoulder inflammation. Maddox has yet to pitch in any game this year after posting good numbers last season, only giving up one run in 17 innings of action.

Baltimore’s submarine relief pitcher has blown two previous save attempts this season but had a clean inning Friday as he struck out two and earned his first save this season as the O’s beat the Indians 3-1 on Friday. It was O’Day’s 20th save of his MLB career.

Tucker had a five-RBI game in Atlanta’s series opener with the New York Mets Thursday. That performance temporarily put the left fielder in a tie with Bryce Harper for most RBIs in the NL. As of Saturday, Tucker has the fifth most RBIs in baseball with 18.

Zunino struggled at the plate in his first three games back with the Mariners, striking out in six of nine plate appearances against Texas. His only stat in those first three games was scoring a run after having to get hit by a pitch to get on base. Zunino’s first hit of the season came Monday as he homered off White Sox pitcher Carson Fulmer.

Gibson is currently on the 7-day DL and has never been called up to the big leagues despite pitching for five years in the minors. He seems to be destined to stay in the minors after puting up good numbers in AA but saw his ERA increase greatly when promoted to AAA.

Magliozzi has moved up to Double-A to play alongside other fellow Gators as a member of the Binghamton Rumble Ponies. He has struggled though, allowing runs in both of his relief appearances with his new team.

Reed has gotten hot this week, hitting three homers over a two-game span Monday and Tuesday and has gone 11-for-15 since Monday. The center fielder is hitting .415 with three home runs and five stolen bases over 13 games.
